Latest in bizzare intestinal ciliates: Troglocorys cava of chimps

by Psi Wavefunction in Skeptic Wonder

Ahhh, I always get excited whenever something new pops up in J Euk Microbiol!This time we have a rather bizzare entodiniomorphid ciliate (remember Litostomatea?): Troglocorys cava, a gut denizen of chimps from Uganda! The following SEM may give you the impression that it's gut has been sliced open with entrails hanging out:Litostomatean intestinal ciliate Troglocorys from the chimp. Note the peculiar concavity (1; CO), filled with "round projections" and a "deep groove" (3; arrows). Scalebar = 1........ Read more »

Attention Please! Attention management for chronic pain

by Bronwyn Thompson in Healthskills: Skills for Healthy Living

A debate that’s been going on for some time is the role of ‘distraction’ in pain management. So many of the people I see have told me they ‘just ignore’ the pain, or ‘I try to distract myself’, or similar, that there isn’t much doubt to me that people habitually use attention management as a [...]...

Did the "Marsupial Lion" Climb Trees?

by Laelaps in Laelaps

Restoration of the skull of Thylacoleo. From The Ancient Life History of the Earth.

Thylacoleo was one strange mammal. A close relative of living koalas, kangaroos, and wombats, the largest species of Thylacoleo were lion-sized carnivores that stalked the Australian continent between 2 million and 45 thousand years ago. Despite its popular nickname "marsupial lion", however, Thylacoleo was quite different from any feline predator. Even though its long forelimbs were tipped with retractable........ Read more »

Chemophobia and risk

by sciencebase in Sciencebase Science Blog

As a chemist by training, I’ve always been loath to give credence to unfounded criticism of synthetic chemicals that might stoke up chemophobia. Indeed, on several occasions I have written about how our bodies have evolved to cope with all kinds of chemicals regardless of whether they are synthetic or “natural”. I’ve never been a [...]Chemophobia and risk is a post from: Sciencebase Science Blog

What’s The Use of a Cancer Marker?

by Rick Scavetta in DNA Dude

For men, prostate cancer accounts for 25% of all cancer cases. But diagnosing the cancer is not without controversy.
The usual method of detecting the cancer is by screening for Prostate-Specific Antigen (PSA), which can lead to early detection and treatment of the disease. Some studies have shown that the PCA test results in high amounts [...]... Read more »

Breeders not so bad after all

by Jeremy in Agricultural Biodiversity Weblog

Speaking of evil plant breeders:
It is generally thought that continuous selection among crosses of genetically related cultivars has led to a narrowing of the genetic base of the crops on which modern agriculture is based, contributing to the genetic erosion of the crop gene pools on which breeding is based.
But this may be another faulty [...]... Read more »

Obesity the new #1 preventable cause of death - now what?

by Yoni Freedhoff in Weighty Matters

A study published last week in the American Journal of Preventative Medicine estimated quality-adjusted life years lost to both smoking and obesity. Rather than going into the nitty-gritty of the study, and rather than opining on whether or not their stats are true or just statistical sleight of hand, I think the evidence would suggest it quite fair to simply conclude that obesity, like smoking, is very bad for your health.So how many Canadians die a year due to obesity and diet related diseases........

The Neuroscience of Curiosity

by Dr Shock in Dr Shock MD PhD

Part of practicing medicine is the recognition of patterns. You need to get the symptoms, physical examination and lab results and review the data to recognize the big picture called diagnoses. The only difference between residents and specialists is the speed at which they arrive at the correct diagnoses. The specialist mostly get there quicker. [...]

I cannot even count the number of times when I have been denied access to a journal article I needed.  Oftentimes, it was while I was working on a paper in college and couldn’t read the paper that all the other scholars cited, or the paper that supported an argument I was trying to make.  [...]...

Computer-assisted killing for conservation

by CJA Bradshaw in ConservationBytes

Many non-Australians might not know it, but Australia is overrun with feral vertebrates (not to mention weeds and invertebrates). We have millions of pigs, dogs, camels, goats, buffalo, deer, rabbits, cats, foxes and toads (to name a few). In a continent that separated from Gondwana about 80 million years ago, this allowed a fairly unique [...]... Read more »

Two tools for screening risk: STarT Back Tool and Örebro Musculoskeletal Pain Screening Questionnaire

I wrote yesterday about the difficulty there is in grouping patients so that the right treatment is given to the right person at the right time. Today’s post coincidentally follows a similar line – two screening tools that discriminate between ‘high risk’ and ‘low risk’ people with low back pain. The value of [...]... Read more »
